TO ALL WHOM IT MAY CONG'ERN:

Be it known that I, HENRY T. B UFEINGTON, Ir., of the'city of Buffalo, county of Erie, andState of New York, have invented a certain new and improved "Pile or vFagot for Wrought-Iron B emsg and I do hereby deelare'that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, Vmaking e'. partoi'- this specification, in which- Figure I is a cross-section of my improved pilef Figure II is a side elevation. FigureIII is a plan of' same. The nature of my invention consistsf First, in so arranging, land combining the several pieces forming the pile 'as that the web, or the middle plate or plates thereof, shallipass through and entirely'div-ide the' angeepiece's, v'rhereby the outward spreading of the flanges is prevented, anda more perfect welding of theA Bange-pieces to the iveb secured than in other known 'forms'of fagots. v

' Second, in 4forming theweb of sectional plates, having their fibre running transversely, and` extending through and dividing the ange-pieces, in combination'jwith longitudinalside binding-plates filling between the ianges, said crossing of the fibre giving a stronger and more perfect beam.v i

Third,` in forming T-ends on one, tworior more of'the crossweb plates, so that' they 'may act as hinders, to hold the flange-pieces 'to the longitudinalside plates. I y

Like letters refer to like parts inA each offthe'gures.

The web of the beam `is composed of the middle cross-plates A, and side binding-plates B, while the flanges are composed of the form-bars C@ l A A I The middle plates arearrangedwith their` fibre running transversely through the' pile, their outer, ends being ii'ush` with the ontsideofthe flange-pieces, and entirely separating the same. i'

Theside binding-plates Brun lorigtudinally,'so that their fibre crosses-that ofthe middle plates `.A. The

A anges vare placed upon'the middle'pla't'e, and the sideplates fill' in between them, the inner sides ofthe anges being rebated, as shown at D, vto receiveftheedges of vthe side'plates.

One or more of thevcross-plntcs is furnished yvith a T-head ateach end, as shown at E, which `laps over I on to the" -flanges, and holds them against the side plates, thus` holding the pile together in th'direction of its depth. Y

At F are shown clamps, appliedto the ends of the pile, and binding the'side plates together, thus securing the pile in the direction of its breadth. v I

Inl chnrgingthe pile in the furnaces, it should belaid on its side, in which position all its parts are held.' irmly together. It isralso'in this position that it is'passed throulghthe"rolls. v

It wil-l he observed that the principal lines upon which the ilangesweld tothe web are at right angles to the direction of the pressure received in passing through the rolls, and that consequence-the welds must be of the most perfect character. This fact is'due to the extension of the middle web through the flanges. In other piles of which I have knowledge, the principal lines upon which the iaingesv weld to the -Web are parallelv to the direction of prc'ssure,iby reason of' the contiguousiianges being formed in one plate, against the'centre 'of \\'hiclrt he web nbuts, so thntvthe rolls cannot exert an e'icent pressure to produce the ivelds, and they are conseqnentlyoften imperfect.

-The crossing of'the fibre offthe web also insures thc soundness of the beam, and increases its.strength. Having thus described my invention, what I claim, and desire to secure by Letters Patent,ris 1. The sectional web-platcs A, arranged'with their ibres running transversely'through the pile in combi- 'nation with the longitudinal sideibinding-plates B, as und -for the purpose setl forth.

Q. The cross clamp-plates, prorideclivith the Tfheads E, in combination with the- {lange-pieces C, and side binding-plates B, :is and for the purpose-set forth. v
